Solution
The power supply was changed from a large diesel generator to a small diesel generator plus energy storage. The static pressure pile driver is now entirely powered by the energy storage. When the energy storage is insufficient, the diesel generator is activated to supplement power, and then shut down after power replenishment is complete. The diesel generator can operate at its optimal efficiency point, and the uptime is significantly reduced.
